Yes, you can get faster after 40. The key adjustments: reduce training volume but maintain intensity, extend recovery to 72-96 hours between hard sessions, add two strength sessions per week, and fuel for performance rather than restriction. Trained masters athletes lose only 5% VO2max per decade compared to 10% for sedentary people -- and most over-40 cyclists have never trained with proper structure, meaning there's significant untapped potential.
The standard narrative about cycling and ageing says VO2max declines 10% per decade after 30, you lose muscle mass, recovery takes longer, accept it and adjust your expectations. That narrative is incomplete. The research consistently shows that trained athletes experience far less decline than sedentary people.
This is the broad evergreen overview.

What Actually Changes After 40
VO2 max does decline — but the rate depends entirely on training. Sedentary adults lose about 10% per decade. Consistently trained endurance athletes lose closer to 5%. And some research suggests that masters athletes who maintain high-intensity training see even less decline.
Recovery takes longer. This is real and non-negotiable. The 48-72 hour recovery window that a 25-year-old needs between hard sessions becomes more like 72-96 hours at 45+. Ignoring this leads to overtraining, not toughness.
Muscle mass decreases (sarcopenia). Starting around 30, you lose approximately 3-5% of muscle mass per decade if you don't actively maintain it. For cyclists, this means declining power output — unless you strength train.
Hormonal changes. Testosterone and growth hormone decline gradually. This affects recovery, muscle synthesis, and bone density. Again, training (especially strength training) partially offsets these changes.
The Good News
Most cyclists start structured training in their 30s or 40s. They have years of untapped physiological potential. A 45-year-old who starts polarised training, proper fuelling, and gym work for the first time will see dramatic improvements — sometimes exceeding their 25-year-old self who rode unstructured every day.
Joe Friel, author of The Cyclist's Training Bible and Fast After 50, was on the podcast — and he's been writing about and coaching masters athletes for decades. His consistent message: the principles don't change with age. The dosing does.
The Training Adjustments
1. Reduce volume, maintain intensity. This is the single most important adjustment. At 25, you can handle 15 hours of training. At 45, 8-10 hours of well-structured training will produce better results than 15 hours of junk miles. Keep the hard sessions hard. Reduce the easy volume slightly.
2. Extend recovery periods. If your plan calls for hard sessions on Tuesday and Thursday, consider moving to Tuesday and Friday. Give your body the extra day.
3. Prioritise strength training. This is non-negotiable over 40. Two gym sessions per week focusing on the posterior chain will offset muscle loss, improve bone density, and directly translate to power on the bike. Our S&C course has the complete programme.
4. Fuel better, not less. The temptation is to eat less as metabolism slows. But under-fuelling compromises recovery — which is already your limiting factor. Eat to perform using the fuel for the work required framework, focus on protein adequacy (1.6-2g/kg), and let body composition take care of itself.
5. Sleep more, not less. Recovery happens during sleep. If anything, the over-40 cyclist needs more sleep than their younger self, not less.
Key Takeaways
- VO2 max decline is real but dramatically reduced with consistent training (5% vs 10% per decade)
- Most over-40 cyclists aren't near their ceiling — there's room to improve
- Reduce volume, maintain intensity — 8-10 quality hours beats 15 junk hours
- Recovery periods need to increase — consider an extra day between hard sessions
- Strength training is non-negotiable — 2 gym sessions per week minimum
- Fuel for performance — under-fuelling is worse over 40 because recovery is already the limiter
- Use our FTP Zone Calculator to set accurate training zones — precision matters more when training volume is limited
- The principles don't change with age. The dosing does.
